3 Claims.

This invention relates to reeds, used in warping machines or the like,for the purpose of spreading the warp ends uniformly as the same are fedin a sheet to a beam preliminary 'to the weaving of the fabric. Morespecifically considered, the invention relates to reeds of the typewhich are known as fan reeds, in which'the reed dents are spread fromthe bottom upwardly so that the same are more widely separated at thetop than at the bottom. This arrangement is provided so that by raisingor lowering the reed to the proper position, the warp threads which passtherethrough will be evenly disposed as the same are wound on the beam.

The principal object of the present invention is to provide a novel formof reed, for use in warping machines and the like, which is soconstructed and arranged that a greater spread of the reed dents isobtainable, thus reducing the number of reeds required to make up acomplete set for a particular warping machine.

The nature and characteristic features of the invention will be morereadily understood from the following description taken in connectionwith the drawing, in which Figure 1 is an elevational view of a reed,for warping machines and the like, embodying the main features of thepresent invention.

Fig. 2 is a transverse section thereof, taken on the line 2--2 of Fig.1.

It should, of course, be understood that the description and drawingherein are illustrative merely, and that various modications and changesmay be made in the structure disclosed without departing from the spiritof the invention, for example, in the drawing there is illustrated atype of construction in which the reed is made entirely of metal withthe dents soldered in place, but, on the other hand, the reed could, ifdesired, be made of the common pitch band construction, or in any `otherpreferred manner.

Referring to the drawing, in the particular embodiment of the inventiontherein shown, the reed dents 5, which are spread from the bottomltoward the top in a fan like arrangement, are of the usual type andmade of thin at strips of metal.

As shown, the dents 5 are spaced by being disposed in the convolutionsof the usual coil springs 6 and I at the top and bottom of the reed,also on each side of the reed, at the top and bottom, the facing strips,8 and 9, forming portions of the frame, are provided. All of the Dartsabove mentioned are soldered to each other in the usual and customarymanner.

At each end of the reed, immediately adjacent the last dent thereof,there is provided a thicker metal strip l0, which serves to reinforcethe structure, and is fixedly secured to the other parts by soldering orotherwise'.

Also, at each end of the reed, there is provided a strut Il, the lowerportion l2 of which extends vertically, and theupper portion I3 of whichis inclined at the same angle as the adjacent end dents and the stripl0. The members Il constitute the end struts of the frame and areiixedly secured at their upper and lower ends t0 the facing strips 8 and9, at the top and bottom of the reed respectively.

By this peculiar arrangement of the end struts l I, arnuch greaterspread of the reed dents is possible and as a result thereof, a smallernumber of reeds will be required in a given set required to equip awarping machine. The vertical portions of the end struts Il will extendbetween the side frames of lthe warping machine but, as the plane of thewarp sheet is above the tops of the side frames of the warping machine,the upper corners of the reed may extend over said side frames and inthis manner the range of the reed will be greatly enlarged.

I claim:

1. A reed for warping machines and the like comprising a plurality ofdents made of thin flat metal and arranged in fan like formation, and aframe for supporting said dents, said frame having top and bottomlmembers and end struts connecting said top and bottom members, theupper portions of said end struts being inclined outwardly substantiallyparallel to the dents at the respective ends of the reed, and the lowerportions of said end. struts being substantially vertical, andreinforcing strips disposed immediately adjacent the end dents andextending parallel thereto, said reinforcing strips being interposedbetween the end dents and the end struts of the frame.

2. A reed for warping machines and the like comprising a plurality ofdents made of thin flat metal and arranged in fan like formation,spacers for the upper and lower ends of said dents, whereby said dentshave a greater spacing at their upper ends than at their lower ends, anda frame for supporting said dents, said frame having top members securedto the top ends of the dents along the opposite outer side edgesthereof, bottom members secured to the lower ends of the dents along theopposite outer side edges thereof and extending beyond the lower N endsof the outenmost dents, and end struts extending between said topmembers and said bottom members and secured to said members at the outerends thereof, said end vstruts at the upper portions thereof beinginclined substantially parallel to the dents at the respective ends ofthe reed and the lower portions of said end struts being substantiallyvertical.

3. A reed for warping machines and the like comprising a plurality ofdents made of thin at metal and arranged in fan like formation, spacersfor the upper and lower ends o f said dents for spacing said dents attheir upper ends at least twice as far as at their lower` ends, and aframe for supporting said dents, said frame having top strip memberssecured to the' topv ends of -the dents along the opposite outer sideedges thereof and beyond said spacers, bottom strip members secured tothe lower ends of the dents along the opposite outer side edges thereofand extending beyond the lower ends of the outermost dents, and endstruts extending between said strip members and said bottom strip--membersvand secured between said members at the outer endsv thereof,said end struts at the upper portion thereof being inclinedsubstantially parallel lto the dents at the respective ends of the reedand the lower portions of said end struts being substantially vertical.
